How to make a sketch from a pattern?

I have this extruded cut pattern made from a couple of straight slots, and of course I've now been asked to make it an outline. I managed to create a composite curve, which was pretty tedious, so I wonder if there's a more efficient way to approach this task?

Create a sketch on the face where the cut starts, then use the "Convert Entities" tool. Select the face of the end of the cut and then click the tick.

Thank you. Someone else left a tutorial with the same instructions earlier, but now their post is gone, wonder if something is wrong with the system here.
